Abstract: A crosslinkable silicone material made of a silicone elastomer by polyaddition reaction is provided. The crosslinkable silicone material is especially useful for taking impressions such as, for example, dental impressions.

Abstract: The invention relates to a setting silicone material to give a silicone elastomer by polyaddition reactions, particularly useful for taking imprints, for example dental imprints. The aim of the invention is a material which has a level of hydrophilicity characterised by achieving contact angles &thgr; (cf. FIG. 1 where (1) represents the surface of a film of set silicone material and (2) represents the drop of water deposited on said surface) which can be as low as those from 25 to 27°. The invention is based upon the introduction into the setting silicone material of particularly: (a) at least one non-ionic surfactant comprising an ester obtained by esterification of a C10-C14 fatty acid with a poly(oxyalkylene) glycol of low molecular weight; or a synergistic mixture of (a)+(b) where (b) is at least one non-ionic surfactant comprising a polyalkoxylated C5-C16 fatty alcohol of low molecular weight.
